KEY FASTENER.

Application filed March 2, 1922. Serial No. 540,439.

To all whom it may concern:

Be it known that I, EMIL H. LARKINS, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a new and useful Key Fastener, of which the following is aspecification.

This invention relates to improvements in key-fasteners, and pertainsmore especially to a key-fastener adapted to attach the bow or handle ofa key, which projects at one side of a door from within the key-hole inthe door, to the shank of the door-knob at said side of the door.

One object of this invention is to have my improved key-fastener notonly comprising an upwardly bowed resilient member which is adapted toembrace the upper portion of and seat on said shank and terminates atone end in a downwardly extending arm which has its lower end portionbent as required to form a hook arranged to extend under and thenceupwardly through the bow or handle of the key, but to provide thekey-fastener with a handle-forming member which has one end portionthereof arranged adjacent and extending outwardly from said end of theshank-embraceable member of the keyfastener and comprises an upwardlybowed portion which extends from said end portion to and over theopposite end and circumferentially of and is spaced from saidshank-embraceable member and terminates in the last-mentioned end ofsaid shankembraceable member.

Another object is to facilitate the manufacture of my improvedkey-fastener, and

to render the key-fastener readily applicable to and removable from theshank of the door-knob.

Another object is to render my improved key-fastener reliable in itsoperation and attractive in appearance.

With these objects in view, and to attain any other object hereinafterappearing, this invention consists in certain peculiarities in thecontour and relative arrangement of the different portions of thekey-fastener hereinafter described in this specification, pointed out inthe claims, and illustrated in the accompanying drawings.

In said drawings, Figure 1 is an elevation showing an edge of thelock-containing portion of a door and shows the key in the position it'occupies upon actuating the lockbolt into its operative position andillustrates the application of my improved keyfastener to the bow orhandle of said key and to the shank of the adjacent door-knob. Fig. 2 isa vertical section taken along the line 22 in Fig. 1. I

Referring to said drawings, 5 indicates a door containing a lock 6, and7 and 8 indi cate the latch and lock-bolt respectively of said lock. Thebolt 8 is shown in its looking or operative position, and 9 indicatesthe key-hole in the door. A key 12 projects at one side of the door fromwithin said key-hole and is shown in the position it occupies upon theactuation of the bolt 8 into lts operative position, and my improvedkey-fastener is shown attaching the bow or handle 13 of said key to theshank 16 of the door-knob 15 at said side of the door and consists of asuitably bent single piece of wire having suitable length and stiffnessand comprises an upwardly bowed resilient member 17 formed by thecentral portion of said piece of wire and adapted to closely embrace theupper portion of and shown mounted or seated on the shank 16 which ismounted on the knob-spindle 18 in the usual manner.

One end portion 19 of said piece of wire is arranged below theshank-embraceable central portion 17 of said piece of wire and bent asrequired to form a hook 20 shown extending under and thence upwardlythrough the bow or handle 13 of the key to be fastened when said key isin the position shown upon the actuation of the bolt 8 into itsoperative position.

The other or upper end portion of said piece of wire is arranged in themain above the shank-embraceable portion 17 and preferably not only bentto have its outer end 22 disposed substantially in contact with theouter circumferential surface of said shank-embraceable portion but bentto form a handle arranged largely above and extending circumferentiallyof said shankembraceable portion. Preferably said last-- mentioned endportion of said piece of wire is bent to form a handle comprising anupwardly bowed member 23 which is spaced in the main upwardly from andextends circumferentially of the shank-embraceable portion 17.

To remove the key-fastener from the shank 16 of the door-knob thehandle-forming member of the key-fastener is taken hold of andactuatedasrequired-to unseat the shank-embraoeable member 17; against the actionof its resilience, from said shank, and obviously the keyfastener, uponremoving it from said shank, is free to be lowered to remove the hook 20from the bow or handle 13 of the key.

What I claim is 1. A key-fastener consisting of a single piece of wirewhich has a bowed andresilient, central A portion arranged :-to embracethe upper portionof and .seat on the shanlk of a doorsknoboandwhas.oneend portion there of arranged :below said shankeembraceable portion andbent to formra hook arrangedto extend. under and thence upwardly throughthe boworhandle o f a key to be fastened,sai d piece of Wire having itsupper or opposite end portion bent to form a handle arranged largelyaboveand extendent intermediate portion arranged to embrace the upperportion of and seat on the shank .of a door-knob and has one end portionthereof arranged below said shankembraceable portion and bent to form ahook arranged to extend under and thence upwardly through the bow ,orFhandie of a .key to be ,fastened, said piece of wire having its upperorr-oppositevenol portion bent to form a handlejcomprising an upwardlbowed portion extending circuinferentially of and, spaced :from theafonesaid shank-embraceable portion.
